WORST: Julianne Hough rocked the on-trend polka dot pattern with this eye-catching frock, but we're not too in love with the color she chose.

BEST: Lady in red! Kelsea Ballerini looked gorgeous as ever in this dress with a sexy slit and floral appliqué embroidery at the 11th Annual ACM Honors.

WORST: We've seen better on Sofia Richie! The model looked totally edgy on the red carpet with her all-black ensemble, but we were left underwhelmed.

BEST: Bombshell alert! Kate Upton showed off her fit figure in a tight LBD at "The Layover" premiere. We're totally lovin' this look!

WORST: Tracee Ellis Ross' bold red lip may be on point, but the rest of her outfit was certainly not. We're not digging the mis-matched patterns of her trench coat and trousers.

BEST: Brooklyn Decker is a vision in white! The model and actress looked as cute as can be in a long-sleeved white tea dress.

(Getty)

WORST: Anna Kendrick's pajama-inspired ensemble is one trend that we're just not impressed with.

(Getty)

BEST: Actress America Ferrera dressed to impress in an eye-catching emerald green frock that hit just above her ankles. She paired the dazzling look with accessories -- some jewelry and a clutch -- of the same hue.

Country songstress Kelsea Ballerini dazzled at the 11th Annual ACM Honors in a bright red gown with a sky-high slit and plunging neckline. We think the floral appliqué embroidery on the dress gives it a unique touch! Meanwhile, Kate Upton was a total bombshell in a form-fitting LBD that she paired with some sexy stilettos.

However, there were other stars that donned the worst looks of the week -- Anna Kendrick failed to pull off the on-trend pajama look while Tracee Ellis Ross left us scratching our heads with all the patterns she tried to pull off.

Check out the slideshow above for the best and worst red carpet looks of the week.
